Abstract
The utility model relates to a tensioner. The tensioner comprises a tensioning cylinder, a tensioning spring, an adjusting nut, a locking nut, a limiting device, a stop plate and a predicting film, wherein the limiting device is connected with the predicting film which is connected with the tensioning cylinder, the adjusting nut and the locking nut are arranged on the tensioning cylinder, the locking nut is connected with the tensioning spring which is connected with the stop plate, and the adjusting nut is arranged behind the stop plate. The tensioning cylinder is a combination of a cylinder body and a conical body. The limiting device comprises a limiting plate and a support bearing. Tightness of the predicting film is controlled by extruding of the tensioning spring, and the film cannot exceed an ironing point during extending by the aid of the limiting device, so that stability and reliability of tensioning of the tensioner are guaranteed, and requirements on production are met.
